Self-Organizing Signals: A Better Framework For Transit Signal Priority, Peter G. Furth
Self-Organizing Signals: A Better Framework For Transit Signal Priority, Peter G. Furth
PSU Transportation Seminars
Actuated traffic signal control logic has many advantages because of its responsiveness to traffic demands, short cycles, effective use of capacity leading to and recovering from oversaturation, and amenability to aggressive transit priority. Its main drawback has been its inability to provide good progression along arterials. However, the traditional way of providing progression along arterials, coordinated-actuated control with a common, fixed cycle length, has many drawbacks stemming from its long cycle lengths, inflexibility in recovering from priority interruptions, and ineffective use of capacity during periods of oversaturation. This research explores a new paradigm for traffic signal control, “self-organizing signals,” based …

Using Empirical (Real-World) Transportation Data To Extend Travel Demand Model Capabilities, Michael Mauch
PSU Transportation Seminars
Real-world traffic trends observed in PORTAL and INRIX traffic data are used to expand the performance measures that can be obtained from Portland Metro's travel demand model to include the number of hours of congestion that can be expected during a typical weekday and travel time reliability measures for congested freeway corridors.
